So She Won't be Miss Arithmetic

Rachel returned from the grocery with mom (buy eggs) to inform me of her new information:

Dad: How many eggs are 12 eggs?

Rachel: A dozen. (so proud of her new term)

Dad: And how many eggs are in a dozen? (Follow up just to be sure.)

Rachel: EIGHT! (with as much confidence as her first answer).

But, they are learning other things.
